[2,3] The culprit calcium debris is guided to re-enter the utricle by the aid of gravity.
On VCUG and RGU, prostatic utricle cyst is diagnosed when spontaneous opacification of a diverticulum arising from the prostatic urethra is seen.
The otolith organs, which consist of the utricle and saccule, are sensitive to linear accelerations.
In addition, ductal adenocarcinomas develop from the prostatic utricle, whereas acinar tumors arise from the urothelial tract, which further complicates diagnosis.
Prostatic utricle cysts are embryological remnants of the Mullerian duct, with prevalence rates as high as 4% and 1% in newborns and adults, respectively.
* Benign paroxysmal positional vertigo (BPPV) This occurs when tiny calcium crystals (otoconia) in the utricle (one of the structures of the inner ear) break loose and stimulate sensory hair cells elsewhere in the inner ear.

Cap = capsule; Ach = achene; Fol = follicle; Utr = utricle; Dru = drupe; Sam = samara; Cyp = cypsela; Ber = berry; Cer = ceratium; Sch= schizocarp; Leg= legume; Lom= loment; Car= caryopsis; Coc = coccarium.
One of the most common dizziness disorders, benign paroxysmal positional vertigo, or BPPV, occurs when calcium crystals in the utricle, one of the structures comprising the vestibular system, break loose and stimulate sensory hair cells, causing mild to intense spinning sensations.
Displacement of otoconia from utricle to semicircular canals is held responsible for the development of BPPV.
